I found a substitute for powdered sugar that we tried tonight. 2c cornstarch, 2c non fat dry milk powder, and 1 cup splenda (or similar). Put in a food processor and blend until like powder sugar. well we let my father in law try it and he liked it, but we think it could use a little less cornstarch because it really caused the icing to be really stiff. And i think i'll run each ingredient thorugh the food processor separately first to make it a little more fine.

I just started a cake decorating class and I'm really excited about it. My mother-in-law and sister-in-law are taking it with me, as well. My father-in-law is diabetic and obviously the 2lbs powdered sugar used for the buttercream frosting we learned how to make doesn't mix well for him. I was wondering if anyone have any great diabetic friendly frosting or other dessert ideas??
